Environmental Effects on the Speed of Sound

A detailed analysis of the environmental effects of temperature and humidity on the speed of sound is presented. An overview of the available literature reveals serious shortcomings for practical applications. New graphs, tables, and equations present the findings in a more useful manner for sound reinforcement use. The results show that tight control of temperature and humidity must accompany the popular trend of splitting microseconds when time correcting sound systems. Failure to do so makes precise time correction an exercise in futility.
